Each boy in this family has as many sisters as brothers but each girl has twice as many brothers as sisters. How many brothers and sisters are there? A. 5 boys and 3 girls. B. 3 boys and 4 girls. C. 4 boys and 4 girls. D. 4 boys and 3 girls. - answer _ D Explanation: Lets assume no. of girls = x and boys = y y = (x+1) ----------- (i) As each boy have equal no. of sisters and brothers and he is not included in brothers. so, 1 is for him in (x+1). y = 2(x-1) ------ (ii) as each girl have (x-1) sisters. By solving eq. (i) and(ii) girls = 3 and boys = 4 In a soap company a soap is manufactured with 11 parts. For making one soap you will get 1 part as scrap. At the end of the day u have 251 such scraps. From that how many soaps can be manufactured? A. 25 B. 22 C. 28 D. 30 - answer _ A Explanation: 251 scraps will be used to make 22 soaps with remaining 9 scraps. again the 22 soaps will produce 22 scraps. so 22+9=31 scraps which makes 2 soaps with remaining 9 scraps. Again the 2 soaps will produce 2 scraps. => we have 11 scraps which can be used to make 1 soap with 1 scrap as remaining. Therefore totally,22+2+1=25 soaps. ShortCut By :: Susmito Bhattacharyya simply the resultant number of sscraps needed to make one soap is = 10 scraps so the answer = quotient of (251/10) = 25 Every day a cyclist meets a train at a particular crossing. The road is straight before the crossing and both are traveling in the same direction. The cyclist travels with a speed of 10 Kmph. One day the cyclist comes late by 25 min. and meets the train 5km before the crossing. What is the speed of the train? A. 66 kmph. B. 40 kmph. C. 60 kmph. D. 76 kmph. - answer _ C Explanation: Speed of the train = 60km/hr. Speed of Cyclist travel = 10km/hr. It means, Cyclist travels 5km in 30minutes. If Cyclist comes late by 25 min and meets the train 5km before the crossing means, it shows Train can travel 5Kms in 5minutes. So, speed of train is (5 km/5min) = 1 km/1min = 60km per hour. If a man ate 100 grapes in 5 days, each day eating 6 more than the previous day, how many grapes did he eat on the first day? A. Eight B. Five C. Ten D. Twelve - answer _ A A Shopkeeper divides an ice-cream brick in two halves, then cut one of the halves into several smaller portions of equal size. Each of the smaller portions weights 12 grams. The shopkeeper now has a total of 5 portions. How heavy was the original brick? A. 8 grams B. 48 grams C. 60 grams D. 96 grams E. 120 grams - answer _ D Explanation: As per the question There are 5 portions ( 4 small portions of equal size of one half and one half of original ice-cream brick.) 1 small portion = 12 grams 4 small portion = 4*12 = 48grams Therefore weight of original ice-cream brick = 48*2 = 96 grams Anand packs 304 marbles into packets of 9 or 11 so that no marble is left. Anand wants to maximize the number of bags with 9 marbles. How many bags does he need if there should be atleast one bag with 11 marbles A. 33 B. 32 C. 31 D. 30 - answer _ B Explanation: Given 9x + 11y = 304. x = (304?11y)/9 = 33 + (7?2y)/9 + y So y = - 1 satisfies. Now x = 35, Now other solutions of this equation will be like this. Increase or decrease x by 11, decrease or increase y by 9. So we have to maximize x. next solution is x = 24 and y = 8. So bags required are 32. There is a lot of speculation that the economy of a country depends on how fast people spend their money in addition to how much they save. Auggie was very curious to test this theory.Auggie spent all of his money in 5 stores. In each store, he spent Rs.4 more than one-half of what he had when he went in. How many rupees did Auggie have when he entered the first store? A. 248 B. 120 C. 252 D. 250 - answer _ A Explanation: As he has spent all his money, He must spend Rs.8 in the final store. a simple equation works like this. Amount left = 1/2 x?4 For fifth store this is zero. So x = 8. That means he entered fifth store with 8. Now for fourth store, amount left = 8 so 1/2 x?4=8=> x = 24 For third store, amount left = 24 so 1/2 x?4=24=> x = 56 For Second store, amount left = 56 so 1/2 x?4=56=> x = 120 For first store, amount left = 120 so 1/2 x?4=120=> x = 248 So he entered first store with 248. A bag contains 2 red, 3 green and 2 blue balls. Two balls are drawn at random. What is the probability that none of the balls drawn is blue? A. 10/21 B. 11/21 C. 2/7 D. 5/7 - answer _ A Explanation: Answer: 10/21 Solution: 2 red, 3 green, and 2 blue balls are there. So the probability of getting no blue ball is not selecting any blue ball among the two chosen balls hence 5C2. 5C2/7C2 = 10/21. 7C2 because we can select any 2 balls from 7 balls in that number of ways. There is a toy train that can make 10 musical sounds. It makes 2 musical sounds after being defective. What is the probability that same musical sound would be produced 5 times consecutively? A. 1/32 B. 11/32 C. 1/16 ? -> 100 Cross multiply. =(119 * 100)/85 = (119 * 20)/17 = 7 * 20 = 140 MP = 140 Above cost price = 140 -100 = 40 Two numbers A and B are such that the sum of 5% of A and 4% of B is two-third of the sum of 6% of A and 8% of B. Find the ratio of A : B. A. 2 : 1 B. 1 : 2 C. 1 : 1 D. 4 : 3 - answer _ D Explanation : 5% of A + 4% of B = 2/3 (6% of A + 8% of B) 5A + 4B = 2/3 (6A + 8B) 100 100 100 100 ⇒ 5A + 4B = 2/3 (6A + 8B) ⇒ 15A + 12B = 12A + 16B ⇒ 3A = 4B ⇒ AB = 4 3 ⇒ A : B = 4 : 3
